MAX1132BCAP+

Analog To Digital Converters (ADC) Overview

The MAX1132BCAP+ is a 16-bit, 200ksps successive-approximation analog-to-digital converter (ADC) housed in a 20-pin SSOP package. It operates from a single +5V supply and integrates an input scaling network, track/hold circuitry, clock generator, and a +4.096V reference. The device supports software-configurable unipolar (0 to +12V) or bipolar (±12V) input ranges. Key electrical specifications include a guaranteed integral nonlinearity (INL) of ±2.5 LSB, a minimum signal-to-noise-and-distortion ratio (SINAD) of 85dB, and low power consumption of 7.5mA in unipolar mode. It features SPI/QSPI/MICROWIRE-compatible serial interfaces and three user-programmable logic outputs.

Analog To Digital Converters (ADC) Feature Summary

• Integrates input scaling network for direct conversion of high-voltage signals without external attenuation components
• Includes internal calibration circuitry to correct linearity and offset errors on demand
• Features three user-programmable push-pull CMOS outputs for controlling external multiplexers or programmable gain amplifiers
• Supports both internal and external clock modes with flexible serial interface compatibility

Analog To Digital Converters (ADC) Applications

• Industrial process control systems
• Data-acquisition modules
• Medical instrumentation
• Portable and battery-powered equipment

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'BCAP+' against the manufacturer's current ordering guide to confirm temperature range and packaging details. Ensure the component matches the required INL specification of ±2.5 LSB for your application. Check for RoHS compliance status as indicated in the official datasheet documentation before finalizing procurement.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 16-bit resolution and 200ksps sampling rate are required within a single-supply +5V system. The integrated input scaler eliminates the need for external voltage dividers for signals up to ±12V. Consider the internal reference stability and calibration requirements if operating in environments with significant temperature fluctuations exceeding 10°C.

Analog To Digital Converters (ADC) Part Context

This part belongs to the MAX1132/MAX1133 family of high-speed, precision ADCs. The MAX1132 variant specifically handles wider input voltage ranges compared to the MAX1133. The 'B' grade indicates a guaranteed INL of ±2.5 LSB, while the 'C' denotes the commercial temperature range of 0°C to +70°C. The 'AP' suffix typically signifies the SSOP package type.

Analog To Digital Converters (ADC) Replacement Considerations

Direct pin-compatible replacements within the same family include the MAX1132ACAP+ which offers tighter linearity specifications (±1.5 LSB INL). Other variants like the MAX1133 series share similar architectures but differ in maximum input voltage ranges. Verify interface timing and power consumption differences when substituting.
